Usage VWS-1000A Digital micro-hardness is a new micro-hardness integrating with optics, mechanic, electricity, computer and data processing software. It is widely used in the hardness testing of the metal material and components, especially for the testing of the hardening layer's depth of the slim metal components by the heat treatment. Specialities 1. Complete the software functions, integrating control, calculate, diagnose and test. 2. Easy to convert between HV/HK and HRC. 3. Besides the data is displayed, it can be printed out. 4. Can be connected to the user's computer by the RS232 interface of the instrument, which can make a deep processing to the data. 5. There is a video path in the instrument, in the test sample can be taken photos or video for the image processing. 6. Large range of the hardness testing: 8-2000HV. 7. Direct loading, is served as bend mark 8. Load force is small, also can test slim samples and large with a certain thickness. 9. Small impress only 10 micron.
